Killing Floor

Killing Floor is a co-op survival horror game by Tripwire Interactive. It was released on the 14th of May, 2009, and since then has won 3 Voodoo Extreme awards: Best PC Game of 2009, Best Shooter of 2009, and Best PC Game Expansion of 2009. The game supports up to six players in online co-op mode, or players can choose to brave the horrific specimens alone in solo mode. The aim is to cleanse each area of specimens in waves, until reaching the last and most difficult wave. This wave features the game's boss, The Patriarch, who players must also exterminate in order to survive. Contrary to popular belief, Killing Floor's enemies aren't “zombies” and, in fact, are the leftover “specimens” from a dangerous and ludicrously unethical cloning experiment by Horzine Biotech that went horribly wrong. Weak specimens will just attempt to bite or scratch players, while bigger ones were the first in the program that were armed with weapons, like a blade or chainsaw. Even more advanced weapons, such as rocket launchers and chainguns, were developed for use with the program, but it was shut down before any clones were created with these weapons. However, that didn't stop Horzine's CEO Kevin Clamely from "enhancing" himself with this technology.

In the typical way these things go, the program didn’t want to be shut down. The specimens got loose. No one was left alive to turn off the specimen cloning equipment, and they began to run amok all over London. Well, some of them were running amok. Others were shambling amok or even jumping amok, but the point still stands.

The police were sent in, but that wasn’t even a challenge for the specimens. The first army units hadn’t been warned what to expect. The screams of “It's got a bloody chainsaw!” over the radios probably didn’t do much for morale, as whole units were chewed up; quite literally, in some cases.

This leaves only the players: the few survivors from the first police and army units thrown in. Telling anyone about this extermination procedure would be a breach of the Official Secrets Act 1911, 1920, 1989, and that would be a disciplinary offense. So just get in there and do your bit for Queen and Country…
